IEA: Oil markets are facing unprecedented supply disruptions in Oil & Companies News 13/03/2026 The IEA Oil Market Report (OMR) is one of the world’s most authoritative and timely sources of data, forecasts and analysis on the global oil market – including detailed statistics and commentary on oil supply, demand, inventories, prices and refining activity, as well as oil trade for IEA and selected non-IEA countries. Highlights The war in the Middle East is creating the largest supply disruption in the history of the global oil market. With crude and oil product flows through the Strait of Hormuz plunging from around 20 mb/d before the war to a trickle currently, limited capacity available to bypass the crucial waterway, and storage filling up, Gulf countries have cut total oil production by at least 10 mb/d. In the absence of a rapid resumption of shipping flows, supply losses are set to increase. Global oil supply is projected to plunge by 8 mb/d in March, with curtailments in the Middle East partly offset by higher output from non-OPEC+ producers, Kazakhstan and Russia following disruptions at the start of the year. While the extent of losses will depend on the duration of the conflict and disruptions to flows, we estimate global oil supply to rise by 1.1 mb/d in 2026 on average, with non-OPEC+ producers accounting for the entire increase. The conflict is also having a significant impact on global product markets, with export flows through the Strait at a near standstill. Gulf producers exported 3.3 mb/d of refined products and 1.5 mb/d of LPG in 2025. More than 3 mb/d of refining capacity in the region has already shut due to attacks and a lack of viable export outlets. Runs elsewhere will be increasingly limited due to feedstock availability. IEA Member countries unanimously agreed on 11 March to make 400 mb of oil from their emergency reserves available to the market to address disruptions stemming from the war in the Middle East. Global observed oil stocks were 8 210 mb in January, their highest level since February 2021. The OECD accounted for 50%, Chinese crude stocks 15%, oil on water 25%, with the remainder in other non-OECD countries. Widespread flight cancellations in the Middle East and large-scale disruptions to LPG supplies are expected to curb global oil demand by around 1 mb/d during March and April compared to previous estimates. Higher oil prices and a more precarious outlook for the global economy pose further risks to the forecast. Global oil consumption is now set to increase by 640 kb/d y-o-y in 2026 – down 210 kb/d from last month. Oil prices have gyrated wildly since the United States and Israel launched joint air strikes on Iran on 28 February. Disruptions to Middle Eastern supplies due to attacks on the region’s oil infrastructure and the cessation of tanker traffic through the Strait of Hormuz sent Brent futures soaring, trading within a whisker of $120/bbl. Prices subsequently eased with Brent around $92/bbl at the time of writing – up $20/bbl for the month. Dire straits The global oil market is contending with the ramifications of the war in the Middle East. Beyond the direct damage to energy infrastructure in the region, the crisis has led to a near halt in tanker movements through the Strait of Hormuz. With nearly 20 mb/d of crude and product exports currently disrupted and limited alternative options to bypass the world’s most critical oil transit chokepoint, producers and consumers globally are feeling t
